A system, comprising:
- an airfoil having a static portion, a moveable portion, and a seal between the static portion and the moveable portion, the seal moveable separate from the static portion and the moveable portion, wherein the static portion includes a passageway configured to direct fluid to a seat, the seal at least partially received in the seat, wherein pressure from the fluid flowing through the passageway urges the seal against a leading surface of the moveable portion.
A system, comprising:
- an airfoil having a static portion, a moveable portion, and a seal between the static portion and the moveable portion, the seal moveable separate from the static portion and the moveable portion, wherein the static portion includes a seat, the seal at least partially received in the seat;
- and
- a spring is received in the seat, the seal resiliently retained in the direction of the moveable portion by the spring.
A gas turbine engine, comprising:
- a compressor section, a combustor section, and a turbine section;
- a vane provided in one of the compressor section and the turbine section, the vane including a static portion, a moveable portion, and a seal between the static portion and the moveable portion, the seal moveable separate from the static portion and the moveable portion wherein the static portion includes a passageway configured to direct a fluid to a seat, the seal at least partially received in the seat, and wherein the seal is resiliently retained in the direction of the moveable portion at least partially by a spring.
